[Freeswitch-users] MOH and bypass media

[Brian West]

Please see:

     <!--
         When calls are in no media this will bring them back to media
         when you press the hold  
button 
.                                                                                                                             -->
     <!--<param name="media-option" value="resume-media-on-hold"/> --

         This will allow a call after an attended transfer go back to
          bypass media after an attended transfer.

     <!--<param name="media-option" value="bypass-media-after-att- 
xfer"/>-->

PS you can't get out of the media path when you unhold... FS will be  
in the media path hold button moving forward unless you use the  
uuid_media command to turn it back off.
